looking to get rid of my old inner barrel setup. its a dytac 380mm 6.03 tbb with a lancer tactical gen2 rotary hopup unit with teflon to keep the adjustment wheel from moving freely. served me well for the past year but upgraded to an rhopped barrel. surprisingly accurate at 150+ feet with 2-3 inch groupings. asking $22 shipped. mainly looking for cash but will consider trade offers. thanks!
